Note: I’m not sure which model output corresponds to ET from the flux data: maet, mevap, mpet, or perhaps maet + mevap? Shown here is maet.
Note that there is only one year of overlap in the driver data: 2014. I’ve highlighted this year with a dashed line.
This shows what a big effect CO2 has throughout the past century. It’s much more obvious with the station data because there is less variation in climate, so the trend in increasing NPP is driven entirely by increasing atmospheric CO2.
